WARNING For the combination of the material and the thread and needle, in particular, refer to the explanation table in “Replacement of the needle”. If the needle or thread does not match the material used such as in the case that an extra heavy- weight material (e.g., denim) is sewn with a thin needle (#11 or higher), the needle can break result- ing in an unexpected personal injury. Other precautions ● Do not put the sewing machine under the ● Do not wipe the sewing machine with solvent direct sunlight or in a humid place. such as thinner. When the sewing machine is soiled, put a small quantity of neutral detergent on a piece of soft cloth and carefully wipe off the sewing machine with it. Be aware that the following state can take place since the sewing machine incorporates semi-con- ductor electronic parts and precise electronic circuits. ● Be sure to use the sewing machine in the temperature range from 5ºC to 40ºC. If the temperature is excessively low, the machine can fail to operate normally. * The operating temperature of the sewing machine is between 5ºC and 40ºC. Do not use the sewing machine under the direct sunlight, near the burning things such as a stove and candle, or in a humid place. By so doing, the temperature in the interior portion of the sewing machine can rise or the coating of the power cord can melt, causing fire or electrical shock.
Preparing the machine Thread guide Raise the support rod fully, turning slightly until the positioning catches engage (A). Position the thread guide on the thread stand so that the arrow is to the front (B). Attaching the spool holders Attach the separately packed spool holder (equipped with two spool holders pins) to the fixed spool holder, by pushing until it snaps in place.
Preparing the machine Attaching the foot control Plug foot control into the machine socket (A) and then into the main socket (B). The foot control regulates the sewing speed.
